Deno integration doesn't work with Deno 2.1.5

[aaronpowell]

The Deno 2.1.5 release seems to have changed something in how the Deno app launches, which results in the integration being unable to start apps using deno run, this means that the AddDenoApp does not work with Deno 2.1.5 (although it does seem to work with 2.1.4).

Consider this as a blocking issue if you are using the Deno integration.

Workaround

From my testing, it seems that using the AddDenoTask extension method to run a task defined in the deno.json file does work, and thus, this is the recommended approach until the problem is resolved. Here is an example:

builder.AddDenoTask("vite-demo", taskName: "dev")
    .WithDenoPackageInstallation()
    .WithHttpEndpoint(env: "PORT")
    .WithEndpoint();

Original issue

https://github.com/CommunityToolkit/Aspire/actions/runs/12701892107/job/35407179902

One of the Deno tests has started timing out, need to investigate why.

Edit
I'm pinning this issue as it's blocking CI, and I think it's also meaning that the Deno integration is currently broken.

Looks like this is failing because the oak demo app isn't starting via the DCP when Aspire launches.

Trying to figure out why that is, but it looks like something might have changed in the 2.1.5 release of Deno.

Resource is reporting Finished in the dashboard but has zero in its own console logs. But if I run it from the CLI (ie deno run <args>) it starts properly.

If I try to restart the process from the dashboard, I see this in the logs (from the App Host process, not in the dashboard):
